Background

Images are often the slowest-loading part of a Web page. Reducing the size of an image can have significant impact on how visitors perceive your Web site. This pattern describes techniques for reducing the sizes of images, and it can be applied to images you already use or to images you are about to deploy. This pattern can be used by itself or in conjunction with other patterns for making fast-downloading Web pages, such as LOW NUMBER OF FILES (L1), SEPARATE TABLES (L3), and HTML POWER (L4).
